accelerator

[ak-sel´er-a″ter] (L.)

an agent or apparatus that increases the rate at which something occurs or progresses.

serum prothrombin conversion accelerator (SPCA) factor VII, one of the coagulation factors.

ac·cel·er·a·tor

(ak-sel'er-ā-ter), Avoid the mispronunciation uh-sel'er-ā-ter.

1. Anything that increases rapidity of action or function.

2. In physiology, a nerve, muscle, or substance that quickens movement or response.

3. A catalytic agent used to hasten a chemical reaction. Synonym(s): accelerant

4. In nuclear physics, a device that accelerates charged particles (for example, protons) to high speed to produce nuclear reactions in a target, for the study of subatomic structure, for the production of radionuclides, or for radiation therapy.

[L. accelerans, pres. p. of ac-celero, to hasten, fr. celer, swift]

Patient discussion about accelerator

Q. What herbs are known to be helpful against Arthritis acceleration?

A. mind you- herbs most of the time contain the same medication that pills do but without an exact amount and accompanied with other materials. there is great danger in that area, here is a guide for choosing a herbal supplement that will give you some tips :

By 1954, a particle accelerator capable of accelerating protons to an energy of 5 to 6 billion electron volts (BeV) had been built at the University of California.

Virtual visitors can "walk" through a tunnel housing part of the collider's 27-kilometer-long particle accelerator. Or you can explore brightly painted particle detectors such as the Compact Muon Solenoid experiment (shown), which scientists used to find many of the ephemeral particles created in the LHC's high-energy collisions.

So first, the scientists had to create negatively charged antiprotons in a particle accelerator. Next, they shot a beam of antiprotons into xenon gas to create antielectrons.

Atom's opposite

Of the volume's 29 fiction pieces, Mark Leyner's "I was an Infinitely Hot and Dense Dot" stands out as closest to what might be termed "post-Modern" writing--to the serial TV culture of Arthur Kroker and David Cook's essay "Television and the Triumph of Culture," and to Fredric Jameson's version of post-Modern culture as one that substitutes "intensities" for "feeling." Piled with hilarious non sequiturs, Leyner's style breaks narrative logic down into almost random bits and bytes, yet remains as charged as a particle accelerator: the narrator asks about the soup du jour and is told it is the "primordial soup." Other selections include excerpts from Burroughs' 1969 novel The Wild Boys (which presents the ultimate "family values" nightmare, an opposition group who "eradicate .
